For the most part case cooling fans have been pretty consistent in design. Well Noctua is about to show us that case fans can be improved. The Noctua case fans incorporate several changes from the standard case fans on the market. We will be looking at the NF-R8 (80MM), NF-S12-800 (120MM / 800RPM), and the NF-S12-1200 (120MM / 1200RPM) fans.
